目的 研究广东省居民体重指数、腰围与血压的关系。方法 按照多阶段分层整群随机抽样方法抽取样本 ,调查血压、身高、体重、腰围等指标 ,用描述性流行病学方法进行比较分析。结果 当体重指数为 <1 8 5、1 8 5～、2 4～、≥ 2 8时 ,血压均值分别为 1 1 2 34/70 77、1 1 6 73/73 1 4、1 2 5 71 /78 1 3、1 33 1 6 /82 5 4mmHg,高血压患病率分别为 1 0 3%、1 2 5 %、2 5 7%和 39 2 % ;腰围从正常到腹部肥胖 ,血压均值从 1 1 6 1 9/72 86mmHg上升到 1 2 7 5 9/79 2 4mmHg,高血压患病率从 1 2 4 %上升到 2 9 5 %。当体重指数≥ 2 4或腰围进入腹部肥胖时 ,血压增长速度明显加快 ,高血压患病率显著提高。结论 血压值和高血压患病率随着体重指数和腰围的增加而上升 ,是高血压的重要影响因素。
Objective To study the relationship between body mass index, waist circumference and blood pressure in Guangdong Province. Methods A multi-stage stratified cluster random sampling method was used to collect samples, and blood pressure, height, weight, and waist circumference were investigated. Descriptive epidemiological methods were used for comparative analysis. Results When the body mass index was <18.5, 185, 24-4, and ≥28, the mean blood pressure was 1 1 2 34/70 77, 1 1 6 73/73 1 4, 1 2 5 71 / 78 1 3, 1 33 1 6 /82 5 4mmHg, the prevalence of hypertension was 10 3%, 1 2 5 %, 25 7 % and 39 2 % respectively; waist circumference from normal to abdominal obesity, mean blood pressure from 1 1 6 1 9/72 86mmHg increased to 1 2 7 5 9/79 2 4mmHg, the prevalence of hypertension increased from 124% to 29.5%. When the body mass index ≥ 24 or waist circumference enters abdominal obesity, the blood pressure growth rate is significantly accelerated, and the prevalence of hypertension is significantly increased. Conclusions Blood pressure and the prevalence of hypertension increase with the increase of body mass index and waist circumference and are important factors affecting hypertension.
